Trimming the Tree

Landscaping truly is an art form.  Our own trees either have a carpet of grass surrounding them or are encircled with cedar chips.  On my walk home from our neighborhood branch library, I noticed the trimness and artistic arrangement of plants around this tree.  Now, why didn't I think of that?!

Trees are a many splendored thing!!

My Neighborhood

What an odd looking tree! Anyone know what kind it is? I suppose I could knock on the homeowner's door and inquire. If I see them outside, I'll ask. In the meantime, any suggestions?
